.SH DESCRIPTION
|
||
|
|
The QWSMouseHandler class is a mouse driver for Qt/Embedded.
|
||
|
|
.PP
|
||
|
|
The mouse driver handles events from system devices and generates mouse events.
|
||
|
|
.PP
|
||
|
|
A QWSMouseHandler will usually open some system device in its constructor, create a QSocketNotifier on that opened device and when it receives data, it will call mouseChanged() to send the event to Qt/Embedded for relaying to clients.
|
||
|
|
.PP
|
||
|
|
See also Qt/Embedded.
|
||
|
|
.SH MEMBER FUNCTION DOCUMENTATION
|
||
|
|
.SH "QWSMouseHandler::QWSMouseHandler ( const QString & driver = QString::null, const QString & device = QString::null )"
|
||
|
|
Constructs a mouse handler. This becomes the primary mouse handler.
|
||
|
|
.PP
|
||
|
|
Note that once created, mouse handlers are controlled by the system and should not be deleted.
|
||
|
|
.PP
|
||
|
|
The \fIdriver\fR and \fIdevice\fR arguments are not used by this base class.
|
||
|
|
.SH "QWSMouseHandler::~QWSMouseHandler ()\fC [virtual]\fR"
|
||
|
|
Destroys the mouse handler. You should not call this directly.
|
||
|
|
.SH "void QWSMouseHandler::calibrate ( QWSPointerCalibrationData * )\fC [virtual]\fR"
|
||
|
|
This method is reimplemented in the calibrated mouse handler to set calibration information (from, for instance, the Qtopia calibration screen). This version does nothing.
|
||
|
|
.SH "void QWSMouseHandler::clearCalibration ()\fC [virtual]\fR"
|
||
|
|
This method is reimplemented in the calibrated mouse handler to clear calibration information. This version does nothing.
|
||
|
|
.SH "void QWSMouseHandler::limitToScreen ( QPoint & pt )"
|
||
|
|
Ensures that the given point, \fIpt\fR is within the screen's boundaries, changing \fIpt\fR if necessary.
|
||
|
|
.SH "void QWSMouseHandler::mouseChanged ( const QPoint & pos, int bstate )"
|
||
|
|
When a mouse event occurs this function is called with the mouse's position in \fIpos\fR, and the state of its buttons in \fIbstate\fR.
|
||
|
|
.SH "const QPoint & QWSMouseHandler::pos () const"
|
||
|
|
Returns the mouse position.
